    1. How well does polyester resin adhere to the 'skin' of poured polyurethane foam ? ( if at all ! )

    2. Are there any contact adhesives that are usable for underwater use ?

    1. It doesn't adhere very well, but you can use an intermediate layer of Sika-290 primer to improve adhesion.

    2. There is liquid neoprene, used by Mercruiser to seal bellows to the alloy housing. It is also used to repair inflatables.
